Creo simulate - memory allocation

[SB_12702131]

I want to understand the need for the memory allocation limits of 16 Gb for 64 bit machines?? i understand the need of having enough memory for the operating system, but now that machines with 32, 64 and even 128 Gb are comun. 
I am asking this because i have a model that the global matrix profile is around 100 Gb on the last pass of the MPA analysis and I am working on a machine with 128Gb of RAM

Articles:

• "Limit of memory allocation solver setting in Creo Simulate": https://www.ptc.com/en/support/article/CS51761 
• "Creo Simulate warning information "The maximum memory allocation (solram) is 16384 MB." while setting the solver memory allocation in Run Settings dialog box to 32768 MB as the 0.25 times of the physical memory 128 GB": https://www.ptc.com/en/support/article/CS340733 

[SB_12702131]

the first article recommends between 25 to 50% of the physical RAM but the limitation of 16384MB imposes a max of 12.5% of the physical RAM to be alocated. 

Is there any prediction for the new releases?

Hi,

please discuss the problem with PTC Support.

I think PTC Support will tell you that Creo Simulate (Mechanica) has this limit hardcoded.

I hope you know that Creo Simulate sale has ended. Therefore the developm,ent of this software was ended.

Just to expand on this a little bit, what PTC said at the last conference was that they have no plans to sunset the Creo Simulate software. It will continue to be included in future releases of Creo. They did enhance Simulate recently to support composite designs. That being said though, PTC is not actively working on making the Creo Simulate product better. They have partnered with Ansys and are going to sell integrated FEA solutions from Ansys through the Creo product (think Simulate Live and Ansys Simulation modules). As Ansys rolls out new features, they will incorporate that new development into those Ansys modules.

Creo Simulation Elite is included free of charge with all new Creo Design Essentials licenses.

Thank you for the explanation, i did not know that PTC wasn't developing Creo Simulate anymore.

I haven't taken the memory settings seriously for a long time:

msengine.exe takes as much memory as it needs:
